Changes in this build 25 
Request for feedback on JEP 353 integrated in b24
JEP 353: Reimplement the Legacy Socket API" has been integrated
into jdk-13+24. It would be very useful if applications or
libraries using java.net.Socket or java.net.ServerSocket APIs
could test with this build and report any issues found. The JEP
provides information on the system property that can be used to
switch back to the old implementation and that may be useful to
check for behavior differences between the old and new
implementation. It would be very useful to get feedback via the
OpenJDK net-dev mailing list, bugs via the usual channel.
